June 22, 1993 Docket No. 50-382 Mr. Ross P. Barkhurst Vice President Operations Entergy Operations, Inc.

Post Office Box B Killona, Louisiana 70066

SUBJECT:

SAFETY EVALUATION FOR COMBUSTION ENGINEERING OWNERS GROUP REPORT CEN-387-P, REVISION 1, " PRESSURIZER SURGE LINE THERMAL STRATIFICATION EVALUATION" (BULLETIN 88-11) (TAC NO. M72180)

By letter dated March 3, 1989, you responded to NRC Bulletin 88-11 and indicated that Waterford 3 was participating in the Combustion Engineering Owners Group (CE0G) effort to evaluate pressurizer surge line thermal stratification. The staff and its consultant, Brookhaven National Laboratory, have completed their review of the CE0G Report CEN-387-P, " Pressurizer Surge Line Flow Stratification." The staff concludes that the CE0G analysis adequately demonstrates that the bounding surge line and nozzles meet ASME Code stress and fatigue requirements for the.40-year design life of the-facility considering the phenomenon of thermai stratification and thermal striping.

The staff's safety evaluation of CEN-387-P, Revision 1, is enclosed.

Action 1.d of Bulletin 88-11 required licensees to update their stress and fatigue analyses to ensure compliance with applicable Code requirements. The CE0G Report can be used to update plant-specific Code stress reports as required by Item 1.d.

Please verify the applicability of the CEOG bounding analysis in CEN-387-P, Revision 1, to Waterford 3.

In addition, please confirm that all actions required by Bulletin 88-11,. including the updating of the plant-specific stress and fatigue analyses required by Action 1.d, have-been completed.

Your response is requested within 180 days of receipt of this letter.
